330xi Misfire Codes

Couple days ago while driving city streets the car started running lumpy and the SES light came on. Drove the car home. Got these codes

p0300 - Random Multiple Cylinder Misfire

p1348 Pending
p1350 Pending
All read Manufacturer Control. Ignition System or Misfire.

What are the possible causes?

Unrelated code I think p1620 - Manufacturer Control Auxiliary Inputs Auxiliary Outputs, which what I was told is the thermostat. I know I have a slight coolant leak in the area of the thermostat and water pump and was planning a coolant system overhaul before the misfire codes showed up.

The car never overheated. Oil and Coolant are the right color and level.
